Welcome back! If the tutorials here help that's great, but I don't know how old they are and how much has changed in Photoshop since they were written. I've been doing this too long to know the good current tutorials, but
Scrapaneers is a well known site for digital scrapbooking classes. Most have a cost, but the blog has free tutorials. I linked you to an intro scrapping blog post, but if you look around there you'll probably find a lot more that's helpful. They have resources for both Photoshop and Photoshop Elements, but I think the blog post I linked is only for Elements.
